Resize PDF pages
Documents assembled from different sources often mix page sizes, which prints badly. This tool scales every page to a uniform target size — A4 or US Letter — keeping proportions and centering the content.
How to use the Resize PDF tool
Select or drag your PDF.
Choose the target page size (A4 or US Letter) and orientation handling.
Click “Resize PDF” and download the normalized file.
Your files stay on your device
This tool runs entirely in your browser using JavaScript and WebAssembly. There is no upload step and no server processing — open your network panel and check: zero document data is transmitted. It even keeps working offline once the page has loaded.
Frequently asked questions
Does resizing stretch or distort the content?
No. Content is scaled proportionally to fit the target page and centered, never stretched. Small margins may appear when aspect ratios differ.
Does text stay selectable after resizing?
Yes. Resizing applies a vector transformation to the page — nothing is rasterized, so text, links and quality are fully preserved.
Can I mix A4 and Letter in one document?
That is exactly the problem this tool solves — it makes every page the same size so printers and viewers behave predictably.
Is it safe to use this tool with confidential documents?
Yes — and verifiably so. PDFAgent has no upload step: your file is processed by JavaScript running in your own browser and never leaves your device. You can open your browser’s network panel (or even go offline after loading the page) and confirm that no document data is transmitted.
